Problems solved by technology

[0002] Nuts are common fasteners. Traditional nuts generally do not have an anti-loosening function. Since many bolts and nuts are used on machines, after starting the machine, the machine will vibrate a little. Therefore, when the bolts and nuts have been used for a long time , the nuts will loosen or even break away from the bolts, which will have an important impact on the normal operation of the machine

Abstract

The invention discloses a multifunctional locking nut. The multifunctional locking nut comprises an anti-theft cylindrical part, a locking nut, an internally-arranged spring, a limiting step, a rotating sleeving part and a hexagonal locking sleeve. According to the multifunctional lock nut, an internally-arranged spring sleeving ring is added to the nut, thus the situation that the nut is loosened due to the fact that a bolt and the nut are subjected to machine vibration for a long time can be effectively prevented, and furthermore, the locking effect of the nut is enhanced. A rotating sleeving part device is added to the locking nut, thus the internally-arranged spring can be loosened and tightened more conveniently, and furthermore, the locking nut is more convenient to use. By means of the structural manner that the hexagonal locking sleeve is matched with a cylinder with an internal thread, after the nut is locked, the hexagonal locking sleeve is taken down, thus the locking nut cannot be taken down with a common spanner, and furthermore, the locking nut has the anti-theft function.

Description

【Technical field】 [0001] The invention relates to the technical field of fasteners, in particular to the technical field of a multifunctional anti-loosening nut. 【Background technique】 [0002] Nuts are common fasteners. Traditional nuts generally do not have an anti-loosening function. Since many bolts and nuts are used on machines, after starting the machine, the machine will vibrate a little. Therefore, when the bolts and nuts have been used for a long time , the nut will loosen or even break away from the bolt, which will have an important impact on the normal operation of the machine. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the prior art and propose a multi-functional anti-loosening nut. The present invention adds a built-in spring ferrule to the nut, thereby effectively preventing the bolt and nut from being damaged by the machine for a long time. Vibration causes the nut to loosen, thereby increasing the anti...
